Economic expansion and innovation: A comprehensive analysis of Pakistan’s path to technological excellence

To encourage technological and industrial innovation, nations worldwide implement "re-industrialization" and "manufacturing return." This study investigates the relationship between GDP growth, expenditure on research and development, and medium- to high-tech as a percentage of manufactured exports on technological innovation in Pakistan. We evaluated long-run and short-run causal relationships using the ARDL, bound-F test, and ECM regression. The study found a positive relationship between GDP growth and technological innovation in the short and long run. In the short run, with a one-year lag, the analysis reveals a positive and statistically significant relationship between technological innovation, medium-high-tech exports, and GDP growth. In the long run, R&D is positive and significant, while economic growth and technological innovation are positive but not statistically significant. There is a 0.38 percent chance that exogenous shocks will eventually lead to equilibrium in the long run. Based on the findings of this study, it is recommended to allocate resources to research and development, promoting collaborative initiatives, ensuring intellectual property rights, and developing a skilled workforce.


Introduction
Technology innovation is a necessary prerequisite for the progression toward technological innovation and the industrialization of high technology [1].Technological innovation can be defined as the process of creating and implementing new technologies, products, and services that improve the efficiency and productivity of businesses and individuals.Economic growth, on the other hand, refers to an increase in the production of goods and services in an economy, in the increasing standard of living of individuals [2][3][4].Technological innovation has become increasingly important in determining the international competitiveness of enterprises, industries, regions, and countries as the knowledge economy accelerates the process of economic globalization.Countries worldwide are implementing strategies dubbed "re-industrialization" and "manufacturing return" to jumpstart a new wave of technological innovation and industrial innovation.In the case of Pakistan, the relationship between economic growth and technological innovation has been a topic of interest for researchers and policymakers for many years.The country has experienced economic growth in recent years, but the pace of technological innovation could be faster.The slow pace of technological innovation has been attributed to several factors, including weak institutions, inadequate infrastructure, and low investment in research and development.
Since the beginning of the Industrial Revolution in the 18th century, there has been a significant relationship between technological innovation and economic growth.The expansion of economies generates a demand for new and improved goods and services, which drives the development of new technologies.Research and development spending is more likely to occur in industries that experience higher productivity growth rates, resulting in higher levels of technological innovation [5].Promoting technological innovation can be facilitated through trade liberalization, as it fosters increased competition and encourages firms' access to novel technologies and knowledge from foreign markets [6].Nevertheless, the correlation between economic growth and technological innovation is not consistently smooth.In low-income countries, economic growth can harm technological innovation by reducing the incentives for firms to invest in R&D due to increased competition and lower profit margins [7].The Gross Domestic Product (GDP) of Pakistan increased at an average yearly rate of approximately 4.4% over the last decade, making Pakistan a nation that has demonstrated persistent economic expansion of many years [8].However, this growth has not been accompanied by a significant increase in technological innovation, which has limited the country's ability to compete in the global market and prevented an improvement in the standard of living for its citizens.Consequently, Pakistan has achieved a low ranking on the Global Innovation Index, which evaluates nations' innovative capacities and accomplishments [9].Many countries that have successfully maintained their economic growth have invested in research and development (R&D), which has ultimately resulted in the development of cutting-edge technologies [10].However, in Pakistan, the government's investment in R&D has been limited, with just 0.27% of GDP allocated to R&D in 2019 [11].This indicates that Pakistan's R&D spending is significantly below the global average.However, several other factors have hindered Pakistan's technological innovation, one of which is the inadequate education system in the nation, which will have a 60% literacy rate in 2020 [12].As a consequence of this, there is a shortage of skilled workers as well as an absence of an entrepreneurial and innovative culture.In addition, the country's intellectual property rights system is extremely lax, and its infrastructure is woefully inadequate, both of which have acted as barriers to technological innovation [13].Despite these obstacles, Pakistan has made some efforts to promote technological innovation.In recent years, the government has launched several initiatives to encourage innovation, including establishing incubators and science parks and introducing R&D tax incentives.In addition, there has been an increase in the number of startups and entrepreneurs in the country, with some achieving global success [14].
As a result of technological developments, there may be increased opportunities for investment, new job categories, and labor specializations.The expansion of global trade and the provision of various nations with a competitive advantage in their exports are two additional advantages generated by technological developments.Therefore, investments in research and development and emerging technologies are necessary for sustained technological advancement.Very few researchers look at the relationship between R&D and technological innovation on the one hand and medium and high-tech exports on the other [15][16][17][18][19].This contrasts with the many researchers looking at the correlation between economic growth, innovation, and total exports.As a manifestation of this, the current study provides a significant and original contribution to previous research on research and development, medium-high-tech exports, and the relationship between economic progress and technological innovation.This provides valuable insights for policymakers, researchers, and stakeholders promoting sustainable economic development and technological advancement in developing nations.The study utilized three different unit root methodologies to assess the stationarity of the variables based on annual data spanning from 1990 to 2021.The ARDL approach analyzes the correlation between variables through short and long-run estimations.The results of this study add to the expanding literature on the relationship among GDP growth, R&D, and technological innovation.In conclusion, the impact of economic growth on technological innovation in Pakistan has been limited by factors such as low investment in R&D, a weak education system, inadequate infrastructure, and weak intellectual property rights.However, there have been some efforts to promote technological innovation, and the government need to continue investing in R&D and fostering an innovation culture to ensure sustainable economic growth in the long term.
Following the introduction, the body of the paper is organized as follows: In Part 2, we will conduct a literature review on the topic at hand.In Part 3, we will discuss the study's methodology and data visualization.Part 4 contains the empirical data results and their interpretation, and Part 5 includes the conclusion and some policy recommendations.

Literature review
The structural change theory postulates that economic expansion can alter an economy's structure, which in turn can encourage the development of cutting-edge technologies.It supports the hypothesis that economic structure alterations can bring about new gaps for innovative and entrepreneurial businesses [20].Christopher Freeman and others developed the sectoral system of innovation theory.This theory emphasizes the significance of particular industries or sectors in driving technological innovation and economic growth.According to this theory, innovation is not widespread; instead, it is primarily confined to specific fields or fields of endeavor, each of which possesses distinctive technological capabilities and innovation networks [21,22].Kenneth Arrow and others developed the theory of learning by doing, emphasizing the significance of experience and learning in fostering technological innovation and economic growth.Conferring to the theory of "learning by doing," the act of producing goods and services leads to the accumulation of knowledge and experience, which can drive further innovation and productivity gains if the right conditions are present [23,24].These theories offer a variety of explanations for how economic growth can affect technological innovation.Additionally, they highlight the significance of human capital, learning-by-doing, and institutions in encouraging innovation.It has been determined that economic growth is one of the primary drivers of technological innovation in several different countries.Much research has been conducted in the empirical literature looking at how economic growth affects technological innovation.
A study investigated the direct correlation between the dissemination of business ethics and performance in innovation.The results indicated a direct correlation between the diffusion of business ethics and innovation performance [25].An analysis assessed the impact of foreign direct investment, trade, final consumption expenditures, exports, and imports on Romanian economic growth.Short-run analysis indicated that trade and final consumption expenditures positively and negatively affected Romania's economic growth.The evidence showed that foreign direct investment hurt economic growth, whereas variable exports of goods and services had a positive effect.Imports exhibited a negative correlation with economic growth following a positive shock and a positive correlation following a negative shock [26].The study analysed the impact of financial expansion, natural resources, gross domestic savings, and FDI on Pakistani economic development.The GMM analysis indicated that natural resources and foreign direct investment enhance economic growth.FMOLS, DOLS, and CCR analyses indicated that natural resources and foreign direct investment positively impacted Pakistan's economic growth [27].The study examined how military, final consumption, gross national income, broad money, and total reserves affect Pakistan's economy.Exploring variable relationships uses NARDL and robust regressions.Total reserves boosted economic growth during positive and negative short and long run-shocks [28].
China's rapid economic growth in the last thirty years has led to significant problems that need immediate attention, such as resource scarcity, high energy demand, and environmental degradation.Overusing fossil fuels exacerbates the ecosystem and elevates atmospheric carbon levels.The impact of ICT on energy consumption behaviour varies across different sectors.ICT activities can positively impact the environment by reducing energy consumption, but they can also have a negative impact by causing an energy rebound effect [29].The research was to investigate China's rapid economic growth's impact on the country's technological innovation by providing empirical evidence from a panel dataset that included all of China's provinces.They contend that higher levels of economic growth can lead to increased spending on research and development, which can lead to increased levels of technological innovation [30].The study provides empirical evidence from data collected at the firm level in the UK to investigate economic growth's impact on intangible investments such as research and development and the role these investments play in driving technological innovation.According to the findings, monetary expansion can make it more attractive for companies to invest in intangible assets such as intellectual property, which can boost technological innovation [31].In the context of the economy of the United States, research on the relationship between economic growth and technological change has been conducted.They conclude that economic growth may fuel technological advancement through a process known as creative destruction, whereby innovative technologies replace conventional ones [16].A study was conducted to investigate how diffusion of knowledge has on technological innovation in Italy.They contend that economic growth can facilitate the dissemination of knowledge between firms and institutions, promoting innovation and growth [32].Another study examined the relationship between changing technological trends and increasing economic growth in 12 OECD countries.They conclude that the progression of technology has a positive correlation with economic growth and that policies enacted by governments that encourage research and development can have beneficial effects on both innovation and growth [33].In their investigation of the relationship between economic growth and innovation in 10 OECD countries, Luintel and Khan found that economic growth led to increased innovation, as measured by patent applications.The relationship was found to be significant [34].The asymmetric autoregressive distributed lag approach indicates that total reserves have a negative and statistically insignificant impact on Pakistan's economic growth in both the short and long run.Research findings on foreign direct investment reveal that positive shocks significantly and negatively impact Pakistan's economy in both the short and long run [35].
Foreign investments and manufacturing, food, and communication technology exports contribute to Pakistan's economic growth for 1976-2019 time series data.The NARDL method analyses long-term and short-term variable relationships through positive and negative shocks.Short-run analysis shows that exporting communication technology and foreign investment have a positive and negative relationship with economic growth.Manufacturing exports in Pakistan negatively impacted economic development [36].Keller examines the role that international trade plays in developing new technologies within the context of the American economy.He states that expanding international trade can foster innovation by boosting competition among nations and easing the flow of technology from one country to another [37].The authors, Coe and Helpman, investigate how trade liberalization affects the rate of technological advancement and economic expansion in developing countries.They contend that trade liberalization's increased competition can benefit innovation because it makes it simpler for nations to exchange technological know-how [38].Similar to the previous study, the influence of trade on innovation and economic growth in Norway was investigated.They conclude that increased trade can promote innovation and development, particularly in industries vulnerable to international competition [39].Researchers used the Granger causality test to investigate the relationship between the number of patent applications, the share of R&D expenditure in GDP, and GDP per capita from 1996-2015.They found one-way causal relationships between high-tech product exports, R&D spending, GDP per capita, and patent application numbers in the short term.Over the course of several decades, investments in research and development (R&D) spending as well as patent applications have led to an increase in GDP per capita, while high-technology exports have had a negative impact [40].An investigation analysed how social globalization, foreign direct investment inflows, and financial development affect environmental pollution in 107 countries representing the global population.Second-generation cointegration techniques and threshold regression estimators investigate long-term relationships and confirm non-linear connections between the variables.Statistical evidence shows the environmental impact thresholds of foreign direct investment inflows, financial development, and social globalization.Foreign direct investment inflows in lower-middle-income countries lead to a rise in ecological pollution both before and after reaching a certain threshold [41].
In light of the correlation between R&D spending and technological advancement, the vast majority of researchers believed that R&D spending positively influenced innovation.In contrast, a minority of researchers thought it had the opposite effect.The first person to conduct quantitative research on the two, used the sum of copyrights as a pointer to assess innovation.He evaluated the data of 448 large American enterprises by starting a linear model of R&D input, sales, monopoly, and innovation.Based on this, he empirically concluded that R&D input experienced positive effects on the rate of innovation [42].After that, Pakes and Griliches performed an analysis of the data of 448 large American businesses and discovered a substantial positive association between patent applications and R&D input [43].Crepon et al. classified R&D operations into input and output processes.R&D expenditure was used as input, whereas patent and new product sales were used as output factors.The results indicated that the two variables were positively correlated [44].Through the use of the DEA method, Nasierowski and Arcelus were able to determine a positive correlation between R&D innovation efficiency and R&D production capacity [45].According to the findings of Pellegrino et al., research and development (R&D) input can be broken down into two categories: R&D expenditures and personnel input.Both categories were found to have a positive correlation with patent output [46].Both Bogliacino and Pianta believed that the amount of money spent on research and development had a significant effect on the number of new ideas generated by the industry and a constructive impact on the rate of profit growth [47].Zhu et al. examined the hypothesis that R&D input improved regional innovation performance under infrastructure control.The conclusions obtained in the investigation came from an analysis of Chinese regional innovation data over five years [48].In addition, Jefferson et al. and Le et al. both posited the concept that a positive correlation exists between R&D input and innovation output [49,50].Nevertheless, some researchers had concluded that investment in research and development (R&D) did not invariably lead to enhanced business performance and that the intrinsic nature of uncertainty in R&D operations could impede the advancement of R&D toward innovation output [51,52].In contrast to the substantial risk associated with potential returns, the likelihood of success in innovation endeavors was low, suggesting that potential losses would likely surpass earnings.MOTOROLA invested $5 billion in the iridium R&D project at the end of the 20th century, ultimately failing [53].This particular instance served as a paradigmatic example of the futility of R&D initiatives.The industrial sector is crucial for economic advancement, but industrial pollution presents environmental and economic challenges.A study examined how green industrial transformations can decrease Pakistan's carbon intensity.The variance decomposition analysis shows eco-friendly industrial adaptations would have the most significant impact on carbon emissions (11.747%), followed by inbound FDI, technological advancements, and regulatory changes.R&D spending has a negligible effect over time [54].The impact of different types of pollution on our natural resources, health, and lifestyle is escalating.The primary reason for ecological degradation is humans' emission of greenhouse gases, such as carbon dioxide, which can be detrimental if the emissions originate from unsustainable sources [55].An innovative theoretical framework, combining the Armey Curve model and the Environmental Kuznets Curve hypothesis, was utilized to analyse the impact of government spending, income levels, and tourism consumption on CO2 emissions across the 50 US states.This research is essential for policymakers to create efficient pollutionreduction strategies.The study employed panel cointegration analysis to assess the impact of government spending on pollution levels.Tourism development affects CO2 emissions across different US states [56].A "carbon emissions peak" before 2030 and "carbon neutrality" before 2060 are ambitious goals for China.Technological innovations are crucial to implementing this emissions mitigation plan.Due to its rebound effect through economic growth, technological innovations may not reduce CO2.The study used a mediating effects model to examine the microeconomic impact of technological innovations on CO2 emissions through economic development and industrial structure transformation in 215 Chinese cities.The primary findings indicate that technological advancements typically lead to a rise in CO2 emissions in China, both through direct and indirect means.Technology innovations and economic growth influence CO2 emissions, displaying characteristics of the Environmental Kuznets Curve (EKC) [57].
The precise nature and magnitude of the impact of economic growth on technological innovation will vary depending on several factors, such as the particular technology, the stage of its life cycle, the level of investment in research and development, and the overall state of the economic condition, however, it is widely acknowledged that a positive and mutually reinforcing connection exists between the two.This conclusion was reached after reviewing the literature discussed in the previous section.The examination of patent applications about economic growth, medium and high technology exports, and R&D expenditure is deserving of special attention, and the various linkages between these variables must be addressed.To accomplish this goal, the auto-regressive distributed model (ARDL) and the error correction model proposed by Pesaran et al. [58], as well as Pesaran and Shin [59], will be analyzed in the following section.

Research methodology
To establish the association between technological innovation and economic growth, we employ secondary data at the country level, which was obtained from the World Bank database.While patents indicate research output, R&D spending represents the allocation of resources towards innovation [60][61][62][63].Patents are the primary variable in technology, reflecting the essential components of the technological process and, presumably, "correlating with the incalculable facets of technological change" [64].According to Kromann, Skaksen, and Sørensen, there is support for the idea that patents are a reliable indicator of technological advancements within the economy [65].The econometric and statistical software E Views 10 was employed to analyze a time series dataset comprising 32 observations.EViews, a software tool for econometrics, enables users to obtain dependable and unbiased conclusions when analyzing time series data [10,66,67].This research establishes a mathematical equation that elucidates the relationship between the dependent and descriptive variables, incorporating the crucial factors influencing technological innovation in Pakistan.The data about variables was collected over 32 years, from 1990 to 2021.Several statistical tests were used to examine this data, including the Augmented Dickey-Fuller Test for Unit Root, the ARDL bound for cointegration, and the ARDL long form and ARDL error correction for regression.We have developed the following econometric model to conduct regression analysis.
, and B 5 are parameters of the variable, while X 1 , X 2 , X 3 , X 4 , X 5 are independent variables and U t is Error term or random walk.
The real name of the variables can be substituted into Eq (a), resulting in the subsequent equation.

Background of data
Table 1 provides a brief explanation of the study variables, offering a concise summary of the meaning and importance of each variable within the study's framework.Autoregressive distributed lag (ARDL) analysis, developed by Pesaran et al., was used in this investigation.When the variables are stationary at I(0) or integrated of order I(1), the ARDL model is preferred over other econometric methods [58].According to the research goals, this model is superior to others in its ability to predict both the immediate and longterm effects of independent variables on patent applications.In addition to using the ordinary least squares (OLS) method to investigate cointegration across variables, the ARDL methodology is helps calculate short-run and long-run elasticities with a small sample size [69].ARDL model provides flexibility in accommodating variables with different orders of integration.ARDL model is suitable for the independent variable in the model when it is unified of order zero I(0), integrated of order one I(1), or commonly cointegrated [70].However, it is not applicable when any variables are integrated into order two I(2).

Nature and measurement of variables
Table 2 provides measurements of variables and series, along with descriptions of the different codes of variables used in statistical software to execute various models.This enables a thorough comprehension of the data and simplifies the utilization of precise statistical models to analyse the variables effectively.
According to Shahbaz, Islam, and Aamir, the utilization of logarithmic form enhances the accuracy and standardization of data measurement [71].The revised equation can be expressed in the following manner: The U t indicates the presence of variations from the model above in patents.Eq (c) can be reformulated by the ARDL (auto-regressive distributed lag) general model for this research, as represented below: In Eq (1), the variables ΔLTPAT, ΔLGDPG, ΔLFDIN, ΔLRADE, ΔLMHTX, and ΔLUEM represent the respective variations in the natural lag of total patent applications, gross domestic product growth, net foreign direct investment, R&D expenditure, medium and high-tech exports, and total unemployment.The constant α 0 denotes the intercept, the lag operator is represented by k, and the error term or white noise is characterized by u t .In addition, the short-run dynamics are influenced by the variables β j , φ j , δ j , ρ j , θ j , and μ j , whereas the long-run parameters or coefficients are denoted by γ 1 , γ 2 , γ 3 , γ 4 , γ 5 , and γ 6 .
Unit root and cointegration among variables.To mitigate the potential for spurious regression, we employed the unit root test on a dataset that exhibited indications of stability.

Short definition
Patent applications An international patent application has been filed with a national patent office or through the Patent Cooperation Treaty system.Patent applications are filed to protect the intellectual property of an innovation, which can be a product or procedure that provides a new technical solution to an existing problem.
According to the World Intellectual Property Organization (WIPO), a patent offers a time-limited safeguard to the holder, granting exclusive rights to their invention for typically 20 years.

Foreign direct investment
Investments made to gain a controlling stake in a company doing business in a country with a different economic system are known as "foreign direct investment" (FDI).As represented in the balance of payments, it is the sum of equity capital, reinvested earnings, and other long-term and short-term capital.
The difference between fresh investment inflows and withdrawals by foreign investors in the reporting economy is shown in this series as a positive number.
The data is then divided by the gross domestic product (GDP) and sourced from reputable organizations such as the International Monetary Fund (IMF), the Organization for Economic Co-operation and Development (OECD), and the World Bank.
Medium and high-tech exports United Nations Industrial Development Organization (UNIDO) data on the share of manufactured exports that are medium and high technology as a percentage of total manufactured exports.

Research and development expenditure
The Before applying any other statistical test, it is imperative to ascertain the presence of stationary data for the study model [72].The adoption of the ARDL model was deemed appropriate based on the recommendation by Ouattara.This model is particularly suitable for situations where certain variables exhibit stationarity at level I(0), some at first difference I(1), and none at second difference I(2).Lagged dependent variable values and current explanatory variable values are used in the ARDL [72].ARDL bound regression.We used cointegration to create and investigate long-term relationships.Because of the statistical properties described in the Gauss-Markov theorem, cointegration is the more desirable test.The ordinary least squares (OLS) estimator must be unbiased and have the lowest possible variance, according to these statistical properties [73].We used a bound test in the cointegration test, which involved comparing the value of the generated F statistic to the tabulated crucial value [58].It is possible to reject the null hypothesis if the calculated value of the F statistic exceeds the critical value given by the table's upper bound.This indicates that the variables are cointegrated and vice versa [59].No conclusion can be drawn from the data if the estimated F statistic value falls between the critical value's upper and lower bounds [74].If there is cointegration among the variables under consideration, it indicates the need for an error correction model.
Error correction model.The presence of both the short-run form and the error term is observed in the error correction model.It is desirable that the error term exhibit significance and a negative direction.The utilization of a negatively signed numerical value enables the evaluation of the temporal duration required for short-term disturbances to achieve equilibrium in the long term.The formulation of the error correction model is as follows: Eq 2 represents the model's short run and the error correction term (ECT).It serves the purpose of allowing short-run shock adjustment, thereby influencing the pace at which the economy will react to such shocks in the long run.The symbol λ represents the coefficient of the error term, which must possess both negative and substantial values to attain statistical significance.In addition, the model's short-term dynamics are expressed by the parameters β j , φ j , δ j , ρ j , θ j , μ j , and λ j .
CUSUM and CUSUMSQ test.To assess the existence of enduring associations between the variables, the investigation employs the cumulative sum (CUSUM) and cumulative sum of squares (CUSUMSQ) tests, as proposed by brown et al. [75].The tests conducted in prior studies [58,59] have indicated that the ARDL model demonstrates a high degree of fitness.The residual of the error correction model (ECM) can be plotted using these tests.If the statistical values within the plot adhere to critical bounds at a significance level of 5%, the findings indicate that the coefficients of the ARDL exhibit stability.

Descriptive statistics
Descriptive statistics were applied to the raw data, as presented in Table 3.The statistical data indicates that the magnitudes of the means for the variables are generally larger, with the exception of RADE.The analysis of skewness shows that the variables TPAT, GDPG, and MHTX exhibit a normal distribution characterized by a symmetrical shape.Conversely, the non-zero skewness values of the variables FDIN, RADE, and UNEM show that they do not follow a normal distribution.The kurtosis values for all variables, except for TPAT and UNEM, exceed 3, suggesting that these variables are not platykurtic but rather indicate extremely high leptokurtosis.Leptokurtic distributions exhibit a greater likelihood of extreme events in comparison to a normal distribution.Furthermore, the Jarque Bera test serves to demonstrate the disparities in skewness and kurtosis that are present among the variables.The null hypothesis for TPAT, GDPG, and MHTX is accepted based on the probability values obtained from the Jarque Bera test, which are 0.4257, 0.6071, and 0.8239, respectively.These probability values exceed the significance level of 5%.This suggests that the variables reflect a normal distribution.The null hypothesis has been rejected for the variables FDIN, RADE, and UNEM, as indicated by the p-values of 0.000, 0.002, and 0.031, respectively.These p-values are below the predetermined significance level of 5%.Consequently, it fails to follow a normal distribution.

Variables stationarity test
The statistical software package EViews10, widely recognized for its effectiveness in analyzing time series data, was utilized to conduct the econometric modeling for this research.After the ADF, DF-GLS, and KPSS were conducted, the data underwent a transformation using natural logarithms to ensure the accuracy of the results.The assessment of stationarity and order of integration is achieved through the utilization of the unit root test.The utilization of trendy and nonlinear regression models is motivated by the concern that conventional regression techniques may yield spurious regression results.Consequently, the application of unit root tests becomes necessary to proceed with additional estimation.It is necessary to do a unit root test to check the order and stationarity of integration, since trends and nonlinearity can lead to false regression or make it impossible to estimate further without this test.Table 4 presents the results, indicating that the variables FDIN, GDPG, and MHTX show stationarity at both the level and first difference.
However, the variables RADE, TPAT, and UNEM do not exhibit stationarity at the level, but they do become stationary at the first difference in ADF and DF-GLS tests.In KPSS, all variables are stationary at the level and first difference except for unemployment, which is stationary only at the first difference.Thus, we employed the ARDL model due to the presence of an integrated order mixture.This combination of level and first-order integration necessitates the use of the ARDL model for estimation [66].The probabilities of all these variables are statistically significant at a level below 5%.The null hypothesis is rejected when the p-value is less than 0.05.The ARDL methodology is employed for estimation purposes due to the presence of stationary variables that show cointegration at different orders, including I(0) and I(I).Before the ARDL approach, the collection of the lag length in econometric models was typically determined using the vector autoregressive (VAR) model.

Lag length selection
The research utilized the optimal lag order of the vector autoregressive model to determine the suitable lag order, as presented in Table 5. *The criteria for selecting the lag order were determined.The results provide a comprehensive overview of the lag selection criteria utilized in  the implementation of the ARDL-bound test.These findings indicate that the model yields superior outcomes when employing a lag of 3, in comparison to lags 1 and 2.
Furthermore, the values of the Akaike Information Criterion (AIC), Schwarz Criterion (SC), and Hannan-Quinn Criterion (HQ) are -5.30714,0.16411, and -3.68023, respectively.These values represent the lowest possible values across all criteria at lag 3. Consequently, it was determined that lag 3 is the optimal choice for the ARDL model proposed in this study.
In addition, we found the inverse roots of the autoregressive (AR) characteristic polynomial to make sure that the lag length we chose was the right one for the vector autoregression (VAR) method, as shown in Fig 1 .The graph illustrates that the data points contained within the circle provide evidence supporting the validity of favorable outcomes at a lag of three.

ARDL F bound cointegration test
It is significant to use the ARDL bound test to make sure there is cointegration before figuring out the long-and short-term relationships among variables [58].The estimated results are shown in Table 6, which shows that the F-statistic value of 6.056 is greater than the lower and upper bounds at significance levels of 1%, 2.5%, and 5% for total patent applications.As a result, the alternative about cointegration is accepted, and the ARDL bound test shows that there is a long-term association.
The establishment of the long-term relationship between the variables was accomplished through the utilization of the bound test.If the null hypothesis (H0) is equal to zero, it indicates the absence of cointegration.If the null hypothesis H1 is not equal to zero, it means the presence of cointegration.Based on the obtained F-statistic value of 6.0564 and the critical value of 3.79 in the upper bound, we can assert with confidence that the null hypothesis can be rejected in favor of the alternative hypothesis.Consequently, we can conclude that the series under consideration exhibits cointegration.

Long run and short run estimation of variables
The ARDL bound test is used to make sure that there is an association among the variables.The study then looks for the short-and long-run coefficients that are connected to those variables.Table 7 present the cointegration analysis results, explicitly focusing on the short-run to the long-run connection between the dependent and independent variables.Throughout an extended period, the growth of gross domestic product (GDP) and the allocation of resources towards R&D have been found to have a favorable influence on technological innovation in Table 7.The coefficient values associated with these variables are 0.266 and 0.010, indicating that a 1% increase in GDP and R&D expenditure leads to a corresponding increase of 0.2% and 0.01% in technological innovation, respectively.The variables of foreign direct investment, medium-high-tech exports, and unemployment exhibit a significant negative relationship with the dependent variable.Specifically, the coefficients for foreign direct investment, medium high-tech exports, and unemployment are -0.470,-4.780, and -0.307, respectively.The probability values associated with the variables are statistically significant at a 5% significance level.The variables above exhibit an inverse correlation with long run technological innovation.
Table 7 presents the error correction model (ECM) results of the ARDL model.The coefficient of GDP is observed to be -0.038,indicating a negative relationship between GDP growth and technological innovation in the current year.However, it is essential to note that the associated probability value of 0.244 is insignificant.However, following a one-year lag, the GDP growth value becomes positive at 0.172 and exhibits a high level of significance at 0.0004, with a confidence level of 5%.The coefficient value for medium-high tech exports is positive, 1.469, and it is highly significant at a 5% level with a p-value of 0.0000.This implies that a 1% increase in both GDP growth and medium-high tech exports is associated with a respective increase of 0.17% and 1.46% in technological innovation.There exists a negative and statistically significant relationship between research and development expenditure and technological innovation in the short term.In addition, Table 7 displays the estimated coefficients that represent the short-run relationship.The presence of a negative value of -0.380 for cointeq (-1), a T-statistic of -6.857, and a significantly high probability value of 0.0000 suggests long run causal connection among the dependent and independent variables.The value of cointeq (-1) being -0.38 indicates a significant propensity towards the equilibrium point.Hence, the exogenous shocks experienced in the short term will be gradually mitigated over time, with an adjustment rate of 0.38% in the long run.
In conclusion, the ARDL model [59] incorporates the dependent variable of technological innovation and the independent variables of economic growth, R&D expenditure, medium and high-tech exports, foreign direct investment, and unemployment.This model is utilized to assess the long-and short-run causal association between these variables.The estimation of the bound F test is used in cointegration analysis to examine the existence of a long-run relationship between variables.The ECM regression has been employed in this model to analyze short-run coefficient estimates.The study's findings indicate a positive but insignificant association between technological innovation and GDP growth in the long run.while, in the short run, GDP growth with a one-year lag has a positive and significant relationship with technological innovation.The impact of R&D expenditure on technological innovation is positive but weakly significant in the long run, while it is negative and significant in the short run.Additionally, the short run effect of medium-high-tech exports is positive and highly significant, but becomes negative and significant in the long run.

The presentation of these tests in Table 8 and Fig 2 demonstrates the use of diagnostic tests to find errors within the model.The trend of serial correlation The LM test reveals that there is no correlation between the error term and the residual of the model.The current value and past value of the variables are disassociated.The model does not show a serial correlation.The null hypothesis, denoted as H 0 , posits that there is no autocorrelation present.Hypothesis H 1 is not equal to zero.The presence of autocorrelation is observed.The null hypothesis cannot be rejected due to the F-statistic value and corresponding probability being above 0.05, indicating that the model does not exhibit autocorrelation.The corresponding probability value (pvalue) of the F statistic is 0.5702, which is larger than the critical value at 5%.
Heteroskedasticity refers to the phenomenon wherein the dispersion of data points varies across the range of values for the variables under consideration, resulting in a non-constant spread of data over time.The scatter graph exhibits a cone shape, indicating that the standard error of the variables is not constant.This observation suggests that the data shows unequal variability.Table 8 presents the acceptance of the null hypothesis based on the corresponding probability values of F-statistics, observed R-squared statistic, and scaled explained SS of 0.1927, 0.1957, and 0.9564, respectively, which are all greater than the significance level of 0.05.Additionally, the F-statistics exceed the 5% level of significance.This implies that heteroscedasticity in residuals is absent, indicating that the residuals exhibit homoscedasticity, which is a desirable characteristic.Therefore, this research model is free of heteroskedasticity.The null hypothesis, denoted as H 0 , assumes the absence of heteroskedasticity, where the variance of the error term is constant across all levels of the explanatory variable.The alternative hypothesis, denoted as H1, is not equal to zero, which represents heteroskedasticity is present.The analysis indicates that the null hypothesis cannot be excluded due to the fact that the observed r-square and the F statistical probability value exceed the critical value at a 5% significance level.

Normality test
The presence of the Jarque-Bera value and its associated probability in the depicted Fig 2 indicates the normality of the model.If the probability value is greater than 0.05, the null hypothesis (H 0 ) is accepted.This implies that the data for analyzing the error correction model with autoregressive distributed lag (ECM ARDL) follows a consistent distribution.The probability value of the Jarque Bera test, which is 0.855992, is greater than the critical value corresponding to a 5% level of worth.Consequently, the null hypothesis will be embraced, indicating that the residuals exhibit a normal distribution.The null hypothesis (H 0 ) posits that the residuals conform to a normal distribution.In summary, the results obtained from various diagnostic and stability tests suggest that the likelihood ratio (LM) test has a probability greater than 5%, precisely0.5702.This implies that there is no evidence of serial correlation in the model.The p-value of the heteroskedasticity Breusch-Pegan-Godfrey (BPG) test is 0.1927, which exceeds the significance level of 5%.This suggests that we fail to reject the null hypothesis, indicating that no heteroskedasticity is present in the model.The normality test is employed to assess the normality assumption in the model, indicating the absence of specification errors in this particular model, as evidenced by the Jarque-Bera probability value of 0.85599.

Check stability in the model
The research conducted by Brown et al. employed the cumulative sum (CUSUM) and cumulative sum of squares (CUSUMSQ) tests to assess the stability of both short-run and long-run coefficients [75].The CUSUM and CUSUMSQ lines of patent applications exhibit statistical significance at the 5% level, indicating that the ARDL model demonstrates stability and a satisfactory fit over time.Figs 3 and 4 display the outcomes of the CUSUM and CUSUMSQ methods.The examination of the reliability of the short-run and long-run coefficients is conducted using the CUSUM and CUSUMSQ tests [76,77].Figs 2 and 3 display the graphical representations of the CUSUM and CUSUMSQ tests, respectively, which exhibit values that lie within the critical boundaries of 5%.This suggests that the estimated parameters show stability throughout the period spanning from 1990 to 2021.The CUSUM and CUSUMSQ plots also display the recursive residuals, which are relevant for assessing the policy implications.In this stability test, two red straight lines indicate a critical threshold that holds statistical significance at a 5% level.The plotted model is positioned between these two essential limit lines, representing the upper and lower bounds.The model exhibits a high degree of fit, and no discernible deviations are observed.This phenomenon contributes to the enhancement of the practicality, substantiation, and efficacy of a policy recommendation.

Conclusion and policy recommendations
This study aims to analyze the relationship among gross domestic product (GDP) growth, research and development (R&D), and technological innovation.The investigation is based on annual time series data spanning from 1990 to 2021.While previous studies have explored various variables in different regions globally, this research represents a significant and novel contribution as it focuses specifically on the developing nation of Pakistan.The results of this study hold considerable importance on a broader scale and possess the capacity to function as a valuable resource for individuals residing in nations where policy choices are being formulated.The significance of these findings extends to the micro level as well, as they demonstrate that businesses can simultaneously achieve a competitive market presence and foster innovation.These attributes are essential for companies to sustain their position in the market.The researchers in this study aim to assess and examine the correlation between technological innovation and several economic indicators, including the growth of GDP, expenditure on R&D, exports of medium and high-tech products, the inflow of foreign direct investment, and the proportion of unemployment about the overall labor force.Developing nations must allocate resources to research and development, enhance their economies, and apply for patents to ensure that innovation results in improved products and methods for manufacturing.Research and development, along with patent applications, have facilitated economic growth in developing nations.South Korea is renowned for its research and development (R&D) and technological innovation.This country has the highest number of patents filed per person and the most significant research and development investment as a proportion of its Gross Domestic Product (GDP), increasing from 0.4% in 1962 to 4.55% in 2019 [9].China and India achieved comparable levels of success.Countries should possess and enhance their technological capacities in technology innovation, human skill development, and the dissemination of both existing and new technologies.Research and development, along with innovation, enhance technological capacities.New technologies, products, and services are developed and improved.Enhancing workforce skills can improve technical capabilities.This necessitates training employees in the development and utilization of new technology.Utilizing and customizing technologies can facilitate technological advancement in nations.This implies the importation of technologies and the exchange of knowledge and expertise.Capital investment is insufficient to escape the middle-income trap; only technological innovation can achieve this.This will increase investment in research and development (R&D) for new technologies, leading to additional technological advancements.South Korea is recognized for its successful advancement from a middle-income to a high-income status.The country made significant investments in research and development (R&D) and technological innovation leading to the emergence of new industries such as semiconductors and the growth of existing ones like shipbuilding and automobile manufacturing.Singapore's ascent from middle-income to highincome status was facilitated by technological innovation.R&D expenditure increased from 1.5% of the Gross Domestic Product (GDP) in 1990 to 2.2% in 2018.Taiwan is a significant economy that leverages research and development (R&D) and technology to transition from a middle-income status to a high-income status.R&D expenditure increased from 1.4% of gross domestic product (GDP) in 1990 to 3.2% in 2018.
The analysis commences with a descriptive examination, which aims to assess the extent to which the sample represents the entire population.In addition, this analysis seeks to discover whether and how central tendency and variability measurements may be extracted from the sample distribution.Widespread measurements of central tendency include the mean, median, and mode, whereas popular measures of variability include the standard deviation, variance, minimum and maximum variables, kurtosis, and skewness.The results of the descriptive statistics analysis indicate that generally larger magnitudes are observed across the variables, except RADE.The skewness of the variables TPAT, GDPG, and MHTX indicates that they conform to a normal distribution with a symmetrical shape.However, the FDIN, RADE, and UNEM variables do not exhibit a normal distribution.The kurtosis values for all variables, except TPAT and UNEM, exceed 3, suggesting that these variables show extremely positive leptokurtosis.The Jarque-Bera test indicates that the TPAT, GDPG, and MHTX variables exhibit a normal distribution.The null hypothesis has been rejected for the FDIN, RADE, and UNEM variables, as their respective p-values fall below the predetermined significance level of 5%.Consequently, it does not adhere to a normal distribution.The Augmented Dickey-Fuller (ADF) unit root test is employed to ascertain the stationarity of all variables at a significance level of 5% or lower.In this instance, it can be asserted that the null hypothesis was refuted due to the p-value falling below the significance level of 0.05.Certain variables exhibited cointegration at the order I (0), while others were observed to have integration at the order I (1).The VAR lag order of the standard lag length was employed by the author for conducting the ARDL co-integration test.Various criteria, including the likelihood ratio (LR), final prediction error (FPE), Akaike information criterion (AIC), Schwarz criterion (SC), and Hannan-Quinn criterion (HQ), were utilized to determine the optimal lag length for the ARDL model.Based on these criteria, it was determined that a lag length of 3 is the most suitable choice for the ARDL model.Using the inverse roots of the AR characteristic polynomial plot, the author ensured that the choice of an appropriate and optimal lag length within the VAR method was correct.The graph illustrates that the data points within the circular region provide evidence supporting the validity of favorable outcomes at a lag of three.The ARDL Fbound test rejected the null hypothesis of no cointegration.This showed that the variables are linked in the long run.In the concluding phase, ARDL modeling is employed to evaluate the long-term and short-term effects of factors such as GDP growth, expenditure on research and development, medium and high-tech goods exports, foreign direct investment, and unemployment.The strategy is founded upon utilizing ordinary least squares (OLS) and error correction model (ECM) estimations.In the short run, the analysis of data using the autoregressive distributed lag (ARDL) technique reveals a robust and statistically significant positive relationship between medium-and high-tech exports and economic growth after a one-year lag with technological innovation.However, research and development expenditures negatively but significantly impact technological innovation.While, in the long run, a notable and statistically significant correlation exists between technological innovation and R&D expenditure, these results follow the study of [31,30].Conversely, there is a positive but statistically insignificant relationship between technological innovation and the growth of GDP; this result follows the study of [16,[32][33][34].In the context of exogenous shocks, the rate at which long-term convergence to equilibrium occurs is 0.38%.This is indicated by the cointeq (-1) residual with a statistically significant negative coefficient.The author conducted various diagnostic tests, including the serial correlation LM test, the Breusch-Pagan-Godfrey test, and the CUSUM and CUSUMSQ tests, to verify the stability and normality of the ARDL model.These tests confirmed that the model is stable and did not identify any errors.

Recommendations of policy
The study has reached a conclusive finding and policy recommendation that countries aiming to attain advanced technological innovation must not only enhance their level of technological adaptation but also augment their level of technical specialization in the goods they produce and engage in trade.The government must increase its financial allocation towards research and development (R&D) endeavors to foster and advance technological innovation.One potential approach to achieving this objective involves the establishment of research institutes, the allocation of grants to universities and businesses for research initiatives, and the provision of tax incentives to companies engaging in research and development endeavors.Promote collaborative alliances among academic institutions, research organizations, and private enterprises to facilitate knowledge and technology transfer exchange.This objective can be accomplished by implementing collaborative research initiatives, internships, and programs that foster collaboration between academia and industry.Establishing a conducive ecosystem for entrepreneurs and start-ups entails facilitating their access to financial resources, mentorship initiatives, and incubation facilities.This will foster the advancement of novel technologies and solutions.To encourage an environment conducive to innovation and incentivize investment in research and development, it is imperative to establish and uphold comprehensive intellectual property rights (IPR) legislation that effectively safeguards the rights of creators and mitigates the risk of intellectual property infringement.This measure is expected to provide incentives for promoting technological innovation within the nation.One potential strategy is establishing technology parks or clusters dedicated to specific industries or technologies.Clusters have the potential to facilitate the convergence of companies, collaborative researchers, and investors, thereby promoting the exchange of knowledge and fostering an environment conducive to technological progress.Establish strategic alliances with technologically advanced countries through formal agreements, collaborative research initiatives, and programs to facilitate knowledge exchange.This will allow Pakistan to acquire knowledge from internationally recognized exemplary methods and gain access to cutting-edge technologies, thereby expediting the pace of technological innovation.Improve the Caliber of education in science, technology, engineering, and mathematics (STEM) to cultivate a proficient workforce capable of propelling technological advancements.The objectives mentioned above can be accomplished through implementing curriculum revisions, establishing teacher training initiatives, and promoting STEM education across all educational tiers.It is imperative to establish a framework that offers incentives and support to enterprises involved in exporting medium-to high-technology products.This may encompass various initiatives such as export promotion schemes, tax incentives, and support for facilitating entry into global markets.By promoting the export sector, Pakistan has the potential to generate substantial revenue and foster an environment that is conducive to technological innovation.
In broad terms, the policy mentioned above recommendations are designed to establish a conducive atmosphere that nurtures technological advancement through allocating resources towards research and development, facilitating collaborative efforts, safeguarding intellectual property rights, and cultivating a proficient workforce.Nevertheless, the impact of economic growth on technological innovation is contingent upon many factors, including governmental policies, institutional frameworks, and the broader business milieu.Furthermore, the occurrence of technological innovation is reliant upon the unique strengths, capabilities, and priorities of each nation.

Limitations and future research direction
This study's main limitation is that some observations for R&D expenditure needed to be included in the dataset.We were struggling but needed help to retrieve this information from databases like Peen World Table 10, Worldwide Governance Indicators, and World Development Indicators.At the same time, an accurate statistical analysis needs a suitable, adequate, and complete data set [78].Forecasting was employed to cope with the missing data by filling in the average of the two preceding values and dividing by 2 for the succeeding value [10,66].
It is highly recommended that upcoming researchers consider using a substantial sample size and incorporate proxies for innovation to ensure a comprehensive dataset.Additionally, it suggests creating a panel data set for comparing emerging economies like China, India, Singapore, and Malaysia.The authors seek to enhance their comprehension of the connection between economic growth and research and development (R&D) impacts on technological innovation.This will enable them to contribute to the current discourse on the factors influencing technological innovation and provide insights for policy-making geared towards fostering sustainable and inclusive economic development.
